UNITED STATES PATENT OFFICE.

JOHN HOLMES, OF ST. CLAIR, PENNSYLVANIA.

PUMP.

Specification of Letters Patent No. 30,221, dated October 2, 1860.

To all whom it may concern:

Be it known that I, JOHN HOLMES, of St. Clair, in the county ofSchuylkill and State of Pennsylvania, have invented a new and usefulImprovement in Pumps; and I do hereby declare that the following .is afull, clear, and exact description of the same, ,reference being had tothe annexed drawings, making a part of this specication, in which-Figure 1 is a. side elevation of my invention. Fig. 2, a plan, or topview of the same, the suction and forcepipes of the pump being removed.

Similar letters of reference indicate corresponding parts in the twofigures.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A, represents a framing on which a rock shaft B, is fitted in suitablebearings, and C', is a frame attached to shaft B, the upper part of saidframe having the power which operates the pump, applied to it throughthe medium of a rod D, or other device-the frame C, being oscillated orvibrated by the driving power which is applied to it.

E, is a cord or chain which is attached to the upper end of the frame C,and is connected at its lower end to a truck D, which is placed on waysa, a, which are inclined or they may be in a vertical position; they areshown inclined in Fig. l. To the lower end of truck D, there is attacheda rod F, which is connected with the plunger rod F, of a force pump G,this pump is' secured to the lower end of the ways a, and is parallelwith them as shown in Fig. l.

The suction pipe H of the pipe extends down of course into the water tobe elevated,

and the force pipe I, extends up to the height the water is to beelevated. The truck D, is loaded with a weight which should be heavierthan the weight of the column of water to be forced through pipe J. Onthe ways a a stops I), Z), are secured said stops limiting the downwardmovement of the truck.

The operation is as follows: The rod D, draws or pulls the frame C, inthe direction indicated by the arrow and raises the truck D, andconsequently draws up the plunger rod F, the pipe H, and pump cylinderfilling with water as the frame, C, moves in the reverse direction, andthen the truck D, descends by its own gravity forcing the water drawn upby the previous upward movement of the plunger rod, up through the pipeI. The frame C, may have a weight attached to it to counterpoise thetruck D.

By employing the loaded truck D, as a means to force up lthe water thereare no parts liable to be broken as is the case where the ordinary rigidor positive connections are employed and the pump may be operatedrapidly so as to work very efficiently.

I do not claim broadly the idea of counter'- poising the pistons ofpumps, but

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

The arrangement of the loaded truck D, rod F, plunger rod F with thepump G, chain E, frame C, and rod D as and for the purposes herein setforth and described.

JOHN HOLMES.
